Ok. I was skeptical about this ball...surprisingly it is bright. It seems smaller than a normal soccer ball so I measured it. Yep, 27” as stated. I wonder how long the batteries will last. I’ll update this review after the 1st pair die. feels durable. Lights upon kicking. Takes two sets of batteries to light entire ball so make sure you keep lots of replacements on hand otherwise you’ll end up with 1/2 the ball lit.

Size 5 is the official size for professional matches. Therefore, this ball is only available in this size. Do not use this soccer ball on concreted areas. Its unique rubber uses Puma Airlock Valve Technology (PAL) in order to facilitate proper airlock technology. This ball features Perimeter Balance Technology (PBT) which enables it to maintain impressive flight characteristics. https://www.youtube.com/watch?v=j2Xn84L3Kcs
